Systempro M compact ®Technical detailsTM/TS bell transformersOtherfunctionsMODULAR TRANSFORMERSThe range of System pro M compact modular transformers consists of a series of safety transformersfor general use, TS-C 25, 40 and 63 VA in accordance with the IEC-EN 61558-2-6 standard andanother series of bell and chime TM transformers, with maximum secondary voltages of 12-24V anda maximum secondary power of 10-15-30-40VA, as well as TS, with maximum secondary voltages of8-12-24V and a maximum secondary power of 8-16-24VA (some versions of the TS transformers areavailable with an integrated ON/OFF switch), according to reference standard IEC-EN 61558-2-8.Modular safety transformers for general use, continuous functioningThe TS-C safety transformer is an insulation transformer for supplying SELV circuits (with extremelylow safety voltage) or PELV circuits (with extremely low protection voltage). In contrast to the belltransformers, TS-C transformers can be used to continuously supply low voltage loads and theyhave a reduced voltage drop value. Even after a short-circuit they maintain their temperature belowthe specifi ed limits. In addition they are equipped with a thermal sensitive restoring device whichautomatically restores power when the transformer is suffi ciently cooled down or the load has beenremoved.Bell transformers are available in 4 series:Failure-proof for bells TM seriesFollowing a possible anomalous use they will not continue to operate, but they are not dangerous tothe user or to adjacent electric parts: the series includes 8 models with 10, 15, 30 and 40 VA powerand 4, 8, 12 and 24 V output voltages.Short-circuit proof not by construction for bells TS8 seriesEven after a short-circuit they maintain their temperature below the specifi ed limits. In addition theyare equipped with a thermal sensitive restoring device which automatically restores power when therelevant part of the transformer is suffi ciently cooled down or the load has been removed. The TS8series includes 3 models with 8 VA power and output voltages of 4, 6, 8 and 12V.Short-circuit proof not by construction for bells TS8/SW seriesUnlike the previous versions this series is equipped with an ON-OFF pushbutton on the front side thatallows the connection or disconnection of the transformer on the line. The TS8/SW series includes5 models with 8 VA power and output voltages of 4, 6, 8 and 12 V.Short-circuit proof not by construction for bells TS16/TS24 seriesEven after a short-circuit they maintain their temperature below the specifi ed limits. In addition theyare equipped with a thermal sensitive restoring device which automatically restores power when therelevant part of the transformer is suffi ciently cooled down or the load has been removed. The TS16/TS24 series includes 7 models with 16 and 24VA power and output voltages of 4,6,8,12 and 24V.11ABB11/115
